'97 Evinrude 90HP<br /><br />I have oil collecting inside of engine cover around the bottom. Also it's dripping down the lower unit.

Re: Oil inside of engine cover

And what have you checked so far, or done to try and locate the source? 1) It may be injector oil which would point to a leak between the front of the engine and the VRO. 2)It may be a mixture of injector oil and fuel which may be a leaky fuel pump, fuel lines, or carbs. If its #2, you also have a fire hazard as well as a polution situation. A little eyeball work should show where the problem is.

The motor has been gone into before. The previous owner burned a piston and the mechanic said the oil injection may have not been working porperly so they disconnected it. Now I mix the oil with the fuel as needed.<br /><br />So if that's the only way it could accumulate, it would be a fuel leak. <br /><br />I don't notice a fuel ordor.

I'd pull the cover and take a look.Sqeeze the fuel primer bulb and look for leaks.Do the same with the primer bulb on the oil tank.<br /><br />If nothing shows,pull the air silencer,run the motor,and see if the reed plates are spitting fuel out the front of the carbs.<br /><br />Also could be bad hoses on the engine itself.They bleed excess gas from one chamber or another,out of the engine.<br /><br />DHP

Re: Oil inside of engine cover

I had the absolute same thing happen to me about two months ago. Oil under cover running down lower unit everthing like you. I took it to a marina thinking that it was my carbs leaking at the seals, but it ended up being every where my fuel hoses connected it was leaking it cost about $5 in parts to fix. He just put new clamps on. He could see fuel leaking when he pumped up the bulb also. But just to be safe I would replace all clamps, it was a cheap fix, and it has not leaked since.
